Finally, A Real Fix for Your Pontiac’s Shifting Problems
If you’re dealing with a 2006 Pontiac Pursuit that’s shifting harshly, getting stuck in gear, or throwing transmission codes, you know how frustrating it can be. As a technician with over two decades of experience, I’ve seen countless drivers worry that their entire transmission is shot. More often than not, the real culprit is a failing Transmission Control Module (TCM). This VIN-programmed T42 TCM, part number YNXS, is the definitive, reliable solution to get your Pursuit’s automatic transmission operating smoothly again, without a costly trip to the dealership for programming.
This module is the brain of your 4-speed automatic transmission (like the 4L60E family). It controls every shift point, manages torque converter lockup for fuel efficiency, and communicates with the main engine computer. When it fails, it can cause a cascade of issues that feel like a major mechanical problem. By replacing it with our pre-programmed unit, you’re not just swapping a part; you’re restoring the precise, factory-intended performance and communication your vehicle needs.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2007 Cobalt—a close cousin to the Pursuit—that came into the shop. The owner was convinced he needed a new transmission. It would randomly slam into gear and had a persistent P0700 code. We checked the fluid, inspected the solenoids, and everything looked fine. On a hunch, we monitored the TCM data stream and saw erratic commands being sent. After installing a VIN-programmed T42 module, the car drove like it just left the showroom. It’s a classic case where the electronic brain, not the mechanical body, was the source of all the trouble. This is why a quality, correctly programmed 2006 Pursuit Transmission Module is often the smartest repair.
Is Your Pursuit Showing These Telltale Signs of TCM Failure?
A failing TCM can manifest in several ways. Before you suspect a more expensive mechanical failure, see if your car is exhibiting any of these common symptoms. A new module can often resolve these issues in one go.
- ✔ Harsh, jerky, or delayed gear shifts.
- ✔ The vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) are present, especially P0700 (Transmission Control System Malfunction) or various solenoid codes (e.g., P0751, P0756).
- ✔ The transmission refuses to upshift or downshift properly.
- ✔ A noticeable drop in fuel economy.
- ✔ Complete loss of communication with the TCM.
A Straightforward Guide to Installation
One of the best parts about this solution is its simplicity. You don’t need to be a master mechanic to install this 2006 Pursuit Transmission Module. For the Pontiac Pursuit, the process is especially easy.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the vehicle’s computer systems.
- Locate the Module: On your 2006 Pursuit, the TCM is conveniently located on the driver’s side, mounted to the strut tower in the engine compartment. It’s a black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical harnesses from the old module. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s always good practice to use a basic OBD2 scan tool to clear any stored fault codes from the system’s memory. Start the car and take it for a test drive to confirm smooth shifting.

- Frequently Asked Questions
-
Do I need to get this module programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before shipping. It arrives ready for plug-and-play installation, saving you time and money on dealership programming fees.
-
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a very manageable job. On the Pontiac Pursuit, it’s located in an easy-to-access spot on the strut tower and typically takes less than 30 minutes to replace.
-
What is a core charge? Do I need to send my old part back?
There is no core charge for this module. You can keep your old part, so there’s no hassle with return shipping or waiting for a refund.
-
Will this fix a P0700 trouble code?
A P0700 code is a general code indicating the TCM has detected a fault. In many cases where the TCM itself is the source of the problem, replacing it will resolve the P0700 and any related specific codes (like for solenoids). However, you should always ensure the wiring and transmission components are in good condition.
